"Barm 2" is the name under which this horrific clip was recently posted by a channel that appears to specialize in clickbait shitposts where the actual content shown bears some loose resemblance to what it is advertised to be; in this case it is a reference to a comparatively tame Simpsons-based animation by Chris O'Neill, to whose Bart parody the character in this clip looks somewhat similar.
Does anyone have any clue as to the origin of this depravity, and dare I ask, is it part of something bigger with even more horrible content to be uncovered? I'm morbidly curious.
